Structural Health Monitoring
Structural Health Monitoring (SHM) is widely applied to various types of infrastructures including high-rise buildings, bridges, tunnels, etc. It’s used to detect the damage in the structure, locate damage locations, identify types of damages and quantify the severity of the damages. Damages can be resulted from any phenomena from small to large scale such as construction faults, temperature changes, vibrations induced by machine insides building, vibration induced from nearby traffic, wind, fires, severe accidents from vehicles or earthquakes.
Equipment for SHM includes accelerometer, displacement transducer, thermocouple, strain gauges, semiconductor gauges, concrete crack gauges. Real-time measurement is needed and both short term monitoring and long-term monitoring can be used. SHM will help to enable the reparation process if needed very quick, prevent the structures from experiencing higher state of damaging. The SHM includes:
Concrete Crack Monitoring
Tensile Testing in External Structural Tender Boxes in External Segmental Box Girder
High rise health monitoring
Bridge health monitoring
